Is dendrochronology absolute or relative dating

technique for measuring time intervals and dating events and environmental changes by reading and dating the pattern (number and condition) of annual rings formed in the trunks of trees.

The results are compared to an established tree-ring sequence for a particular region with consideration to annual fluctuations in rainfall which result in variations in the size of the rings laid down by trees on the outside of their trunks.

The methods have varying applications, accuracy, range, and cost.

Many new techniques are being developed and tested.

Dendrochronology, the relationship of dated ancient trees with live trees has no SYNONYMS OR RELATED TERMS: chronology CATEGORY: technique DEFINITION: The process by which an archaeologist determines dates for objects, deposits, buildings, etc., in an attempt to situate a given phenomenon in time.

The well-constructed , and combined stratigraphy with pottery typology to produce the first synthesis of southwestern prehistory.

This provided a dating method for the southwestern Pueblo villages.

CATEGORY: chronology DEFINITION: A chronometrically dated chronology which is not yet tied in to calendar years.

CATEGORY: technique DEFINITION: A diagram in the form of a schematized tree with many branching lines at one end and uniting into a single trunk at the other -- used to record the analysis of tree-ring widths for a sample(s).

It is then compared to a master chronology in dendrochronology studies.

Local sequences cannot always be tied to the master sequences established in certain areas from the present day back into prehistory, and therefore the local sequences will 'float' until some link with a known historical date is found.
